How to Use This Calculator
  1. Enter the Number of Smart Contracts — a simple token is 1, an NFT marketplace is 3–5, a full DEX is 5–8.
  2. Set Frontend Complexity: 1 = simple wallet integration, 2 = dashboard with charts, 3 = complex real-time UI.
  3. Enter the Number of Chains — each additional chain adds ~30% development overhead.
  4. Set the Developer Hourly Rate ($) — senior Web3 developers typically charge $100–250/hr.
  5. Toggle Include Audit, then review Total Development Hours, Development Cost, Audit Cost, and Total Project Cost for budget planning.

What each input means

Number of Smart Contracts
Number of Solidity/Vyper contracts to develop. DEX ~ 5-8, NFT marketplace ~ 3-5, token ~ 1-2.
Frontend Complexity (1-3)
1 = Simple dApp (wallet + forms), 2 = Dashboard with charts, 3 = Complex (real-time, social, indexing).
Number of Chains
Chains to deploy on. Each additional chain adds ~30% development overhead.
Developer Hourly Rate ($)
Blended hourly rate for the dev team. Web3 senior devs: $100-250/hr.
Include Audit (0=No, 1=Yes)
Whether to include a security audit in the cost estimate.

What each result means

Total Development Hours
Total estimated hours for all development work.
Development Cost ($)
Total cost for smart contract, frontend, backend, testing, and DevOps work.
Audit Cost ($)
Estimated security audit cost based on contract complexity.
Total Project Cost ($)
Development plus audit costs.
Monthly Infrastructure ($)
Ongoing monthly costs for RPC nodes, hosting, and monitoring.
First Year Total ($)
Project build cost plus 12 months of infrastructure.
Smart Contract Hours
Hours dedicated to smart contract development and testing.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Number of Smart Contracts = 3, Frontend Complexity (1-3) = 2, Number of Chains = 1, Developer Hourly Rate ($) = 150 = 5 input(s) provided
  2. Calculate Development Cost
    Development Cost = totalHours * hourlyRate
    199650 = $199,650
  3. Calculate Total Project Cost
    Total Project Cost = developmentCost + auditCost
    210450 = $210,450
  4. Calculate Total Development Hours
    Total Development Hours = devHours + testingHours + devOpsHours
    1331 = 1331
  5. Calculate Audit Cost
    10800 = $10,800
